In the original Bram Stoker novel, Dracula has three brides,
colloquially referred to as the [Brides of Dracula]
(https://en.wikipedia.org/wiki/Brides_of_Dracula). I thought it would
be a nice touch for NetHack to quietly reflect this by ensuring three
of the vampires of his court are vampire ladies. While this
technically increases the difficulty of Vlad's Tower, the vampires in
Vlad's court are not necessary to fight, and the experience level of
a hero at this point in the game is likely to cause them to spawn as
vampire lords or ladies in any case.
No established names exist for these characters, so I have left them
unnamed.
